It seems that the Register plugin got updated and made a lot of plugins getting errors upon trying to register their plugin into "Register".

>The error:
[SEVERE] Could not pass event PLAYER_INTERACT to Showcase

I wasn't so sure if i had to post this on Register's github but since i'm pretty sure its just that your plugin is using an outdated version of Register (hence the IncompatibleClassChangeError) i decided to post the ticket here.

Apparently, The errors pops up when a player try to buy something/interact with /use showcase.
